Then, the socket 22b is engaged with the rear portion 34 of the housing 30 and attached.

At this time, the mounting axis L1 of the valve 22a is inclined downward toward the hand 60, and the forearm 62 is also inclined forward, so that the bending angle of the wrist becomes loose, for example, a steep angle of about 90 °. Bending is not necessary. For this reason, the bending angle of the wrist can be reduced and the valve replacement work can be facilitated, so that the maintainability of the valve 22a can be improved.
Moreover, since the maintenance opening 25 is formed long in the vertical direction, it is easy to bend the wrist 61 backward.

The valve maintenance for the tail lamp 23 can be performed in the same manner. However, since the bulb 23a of the tail lamp 23 is slightly inclined to the left and right with respect to the bulb 22a of the stop lamp 22, and is at a lower position, the inclination angle of the attachment axis L2 is slightly looser than the attachment axis L1 so that the work can be easily performed. The bending angle of the wrist is adjusted.

Furthermore, since the operations for these valves 22a and 23a can be performed in the vicinity of the upper opening 25a, the operation can be performed without inserting the hand 60 into the maintenance space 32 too deeply.
Moreover, the engagement / disengagement operation of the socket with respect to the rear portion 34 of the housing 30 by the hand 60 is not directly visible, but it is frustrating, but the upper opening 25a of the maintenance opening 25 reaches the lower end of the rear unit 20, so Since most of the work can be performed with visual observation and the fingertip position is easily registered, the workability is improved as compared with the case where the work is performed by groping while the hand 60 is not visible at all.

Further, when replacing the bulb 21a of the winker 21, the forearm 62 is more gently inclined and the hand 60 is inserted into the maintenance space 32, and the hand is bent to the left or right side.
In this manner, when replacing the turn signal bulb 21a, since the bulb 21a is offset from the left and right, the angle of the wrist of the operator tends to be tight. By tightening the inclination of the attachment axis L1 of the valve 22b, the wrist bending angle is reduced and the operation is facilitated, so that the maintainability of the blinker valve 21a can be improved.
In addition, since work can be performed with the fingertips viewed through the maintenance opening 25, workability is improved.

The maintenance lid 15 is located between the left and right turn signals 21. For this reason, the maintenance lid 15 can be set small, and the maintenance opening 25 approaches the left and right turn signals 21, the stop lamp 22 and the tail lamp 23, and the sockets 21b, 22b and 23b of the respective valves are reached. Therefore, it is easy to replace each valve.
In addition, the maintenance lid 15 can be set small, and the distance from the maintenance lid 15 to the stop lamp 22 and the left and right turn signals 21 can be reduced, so that it is easy to replace each lamp bulb.

When the maintenance work is completed, the maintenance opening 25 is again covered with the maintenance lid 15 and fastened with screws 26 and 29. As a result, the maintenance space 32 is closed by the maintenance lid 15, and at the same time, the maintenance concave portion 27 is also closed by the lid lower portion 15 c.

As described above, since the maintenance concave portion 27 is provided on the rear surface of the hanging portion 7 of the rear fender 6, the operator can insert the hand 60 from the lower rear portion of the hanging portion 7, and the wrist 61 is used when replacing the valve. There is no need to bend it greatly, improving workability.
In addition, the maintenance recess 27 provided on the rear surface of the rear fender 6 eliminates the need to increase the size of the lighter more than necessary in order to secure a space for the operator to put in hands, thereby reducing the size and weight of the vehicle. be able to.
In addition, the maintenance concave portion 27 is covered with the maintenance lid 15 and is covered with the drooping side wall 7b in a side view, so that the appearance can be kept good.

Further, a maintenance opening 25 is provided using the maintenance recess 27 provided in the hanging portion 7, and when the hand 60 is put into the maintenance space 32 from the maintenance opening 25, the forearm 62 is put into the maintenance recess 27. Therefore, it is not necessary to form the maintenance opening through the rear fender 6 as in the prior art.

For this reason, sufficient waterproof and dustproof properties can be secured for the maintenance space 32 by the rear fender 6. Also, mud splashed by the rear wheel 2 is likely to adhere to the lower surface of the rear fender 6. If a maintenance opening is provided here, the mud is removed first before maintenance. Since the lid has to be removed, the work becomes troublesome. However, by providing the maintenance opening 25 and the maintenance lid 15 at the rear of the rear combination lamp 8 and the hanging part 7, such a trouble does not occur.

The present invention is not limited to the above embodiment, and various modifications and applications are possible within the principle of the invention. For example, instead of the rear combination lamp 8 in which the turn signal 21, the stop lamp 22, and the tail lamp 23 are integrated, they may be provided independently, and may be at least one of them. In short, a lamp provided at the rear of the vehicle body is sufficient.
